Performance and Emission Analysis of a DI Diesel Engine Fueled with Blends of Ethanol and Methanol in Biodiesel-Diesel-EHN using EGR
Journal Title: International Journal of engineering Research and Applications - Year 2018, Vol 8, Issue 9
Abstract
This study investigates the performance (BTE and BSEC) and emissions (CO, HC, NOx and smoke) of biodiesel-diesel blends of B20, B50 and B100 mixed with methanol and ethanol at 5% and 10% v/v, and 1% 2- ethylhexyl nitrate (EHN). The blends were tested under two conditions (without EGR and with EGR), on a twin-cylinder HATZ 2G40 light-duty direct injection (DI) diesel engine at 3000 rpm at different load conditions (low load: 20%, medium load: 50%, and high load: 80%). Although methanol and ethanol helped reduce the biodiesel’s viscosity, increasing the amount of methanol and ethanol also decreased the biodiesel’s cetane number (CN). Therefore, to overcome this issue, the use of an additive EHN was used as a CN improver to reduce ignition delay and soot formation. The performance and emission results with blends of ethanol and methanol in biodiesel-diesel-EHN were compared to that of base fuels (B0, B20, B50 and B100).
